How well does KI work?

Knowing that KI may not give a person 100% protection against radioactive iodine is important. How well KI blocks radioactive iodine depends on:

  1. How much time passes between contamination with radioactive iodine and the taking of KI (the sooner a person takes KI, the better)
  2. How fast KI is absorbed into the blood
  3. The total amount of radioactive iodine to which a person is exposed
